      Description

      Happens on KQEMU, ROS revision 39272. You need to install FF1/2 and run it. After page is loaded, break into KDBG and set catching on all exceptions (it is vital, as without it the bug doesn`t happen):

      ←[7h♣Entered debugger on embedded INT3 at 0x0008:0x808c1cd2.
      kdb:> set condition * first always
      kdb:> cont

      Then try to type an adress, lets say www.google.pl - as soon as you hit www. Reactos will throw an exception, instead of displaying list with possible urls). It doesnt happen on FF clone - K-meleon, but this browser do not display the url list after first dot.

      Entered debugger on first-chance exception (Exception Code: 0xc0000005) (Page Fault)
